Pressemeddelelse fra LEO Pharma
BALLERUP, Denmark, February 10, 2023 — LEO Pharma A/S, a global leader in medical dermatology, today announced positive results of the DELTA 2 trial. DELTA 2 is the second of two pivotal phase 3 clinical trials with delgocitinib cream, an investigational topical pan-Janus kinase (JAK)-inhibitor, for the potential treatment of adults with moderate to severe chronic hand eczema (CHE).
The trial met its primary endpoint with a statistically significant improvement in CHE after 16 weeks of treatment with delgocitinib cream compared to vehicle, and the treatment was well-tolerated. All or most of the signs and symptoms of CHE were cleared early in the treatment period for a significantly larger proportion of patients treated with delgocitinib cream compared to subjects treated with cream vehicle.DELTA 2 is the second phase 3 trial to achieve its primary and all key secondary endpoints, confirming the positive results of the DELTA 1 trial.
“It is incredibly exciting to see the level of consistency that our DELTA 2 results show in line with the positive DELTA 1 results announced late last year”, said Jörg Möller, Executive Vice President, Global Research & Development, LEO Pharma. “CHE is a condition that we know can have a hugely negative impact on patient quality of life, physical functioning, and ability to work. These results bring us one step closer towards establishing delgocitinib as a best-in-class innovative topical treatment for patients affected by this hard-to-treat disease.”
Subjects who completed 16 weeks of treatment in trials DELTA 1 or DELTA 2 were offered to roll-over to the DELTA 3 extension trial to evaluate the long-term effects of delgocitinib cream.2
Further analyses of the data set will be conducted to determine the full potential of delgocitinib cream in the treatment of adults with moderate to severe CHE. Detailed results from DELTA 2 are planned to be submitted for scientific presentation and publication at a later date.

About the DELTA 1, 2 and 3 Trials
The primary objective for the randomized, double-blind, vehicle-controlled, multi-center phase 3 clinical trials (DELTA 1 and DELTA 2) is to evaluate the efficacy of twice-daily applications of delgocitinib cream compared with cream vehicle in the treatment of adults with moderate-to-severe CHE.3,4
The primary endpoint of the trials is the Investigator’s Global Assessment for chronic hand eczema treatment success (IGA-CHE TS) at Week 16. Treatment success is defined as an IGA-CHE score of 0 (clear) or 1 (almost clear, with little or no disease left) with at least a two-step improvement from baseline. Additional IGA-CHE scores include 2 (mild), 3 (moderate), and 4 (severe).
Key secondary endpoints at Week 16 include reduction of itch and pain scores of ≥4 points measured by the Hand Eczema Symptom Diary (HESD) from baseline to Week 16, as well as at least 75% improvement from baseline and at least 90% improvement from baseline on the Hand Eczema
Severity Index (HECSI) at Week 16. The number of treatment-emergent adverse events from baseline to Week 16 defines the key safety endpoint of the trials.
Subjects who completed 16 weeks of treatment with delgocitinib cream or cream vehicle twice daily in trials DELTA 1 or DELTA 2 were offered to roll-over to the DELTA 3 extension trial. The purpose of this extension trial is to evaluate the long-term effects of delgocitinib.2
About Chronic Hand Eczema
Chronic Hand Eczema (CHE) is defined as hand eczema (HE) that lasts for more than three months or relapses twice or more within a year.5,6 HE is the most common skin disorder of the hands7with a one-year prevalence rate of approximately 9%.8 In a substantial number of patients, HE can develop into a chronic condition.7CHE is a fluctuating disorder characterized by itch and pain, and patients may experience signs such as erythema, scaling, lichenification, hyperkeratosis, vesicles, edema, and fissures on hands and wrists.9
About delgocitinib
Delgocitinib is a first-in-class investigational topical pan-Janus kinase (JAK)-inhibitor that inhibits activation of the JAK-STAT pathway, which plays a key role in the immune system in driving the pathophysiology of chronic inflammatory skin diseases.10,11 LEO Pharma is currently developing delgocitinib in a cream formulation for the treatment of moderate to severe chronic hand eczema (CHE) in adults.
In 2014, LEO Pharma A/S and Japan Tobacco Inc. (JT) entered into a license agreement in which LEO Pharma gained exclusive rights to develop and commercialize delgocitinib for topical use in dermatological indications worldwide, excluding Japan, where JT retains rights.
